Lithium iron phosphate ion battery refers to a lithium ion battery with lithium iron phosphate as a positive electrode material. Ngwa elektrọn dị mma nke batrị lithium-ion dị mkpa maka lithium cobalt organte, lithium manganate, lithium nickel acid, ihe akụkụ atọ, lithium iron phosphate, wdg. N&39;ime ha, lithium iron phosphate bụ ihe dị mma ejiri ugbu a na ọtụtụ batrị lithium-ion.

Ngwungwu batrị lithium iron phosphate ion kwesịrị ịbawanye, kwalite ọrụ batrị lithium dị ala. What is the factor affecting the low temperature energy of the lithium phosphate ion battery pack? For the lithium iron phosphate ion battery pack, industry experts have made more detailed research on its low temperature characteristics, the reasons: 1. Production environment: lithium iron phosphate ion battery Package is a high-tech product that has a large chemical raw material.

Its production environment has a high requirements for temperature, humidity, dust, etc., and if there is no control, the battery quality will fluctuate. 2, adịghị mma conductivity, lithium ion mgbasa ọsọ ngwa ngwa.

Mgbe ụgwọ dị elu na mwepụta, ọnụ ọgụgụ ahụ dị ala, nsogbu a bụ ebe siri ike igbochi mmepe nke ụlọ ọrụ phosphate nke lithium iron. Lithium iron phosphate anaghị enwe ọtụtụ ngwa ngwa n&39;oge, nke a bụ okwu dị mkpa. 3, mmetụta nke ihe ahụ, lithium iron phosphate positive electrode n&39;onwe ya adịghị mma, na polarization na-adịkarị mfe na polarization, na-ebelata ikike nke ikike; ogwe na-adịghị mma dị mkpa maka ụgwọ okpomọkụ dị elu, n&39;ihi na ọ na-emetụta nsogbu nchebe; Otu, nwere ike ịbawanye viscosity na obere okpomọkụ, nkwụsịtụ ion lithium ga-abawanye; nke anọ bụ ihe nkedo, nke a dịkwa oke ibu.

How to improve the lithium iron phosphate ion battery pack low temperature performance? We raise low temperature performance of lithium iron ion battery pack from the positive electrode, negative electrode, electro-hydraulic, and binder. N&39;ihe dị mma, ọ bụ ugbu a nanomechanically, nha nha ya, nguzogide ya na ndị na-eto eto AB planar axis ga-emetụta njirimara nke batrị niile dị ala. Usoro dị iche iche nwere mmetụta dị iche iche na electrode dị mma, na njirimara dị ala okpomọkụ nke batrị mere site na 100 ruo 200 nano-particle dayameta phosphate, nke nwere ike hapụ 94% na -20 degrees, nke bụ akụkụ nke dayameta nke nanofence na-ebelata ụzọ nke njem njem, Ọ na-eme ka arụmọrụ nke obere okpomọkụ na nkwụsị, n&39;ihi na nkwụsị nke lithium phosphate na-ejikọta ya na nti electrode.

N&39;ịtụle odori e ji mara si na-adịghị mma electrode, na ala okpomọkụ odori nke lithium ion batrị dị mkpa, gụnyere urughuru size nke urughuru size na pitch nke ọjọọ electrode, họrọ atọ dị iche iche wuru graphite dị ka ihe ọjọọ electrode na-amụ dị iche iche oyi akwa spacing na urughuru size ụzọ obere okpomọkụ mmetụta nke e ji mara. Site na ihe atọ, graphite ọka nke oyi akwa dị ukwuu, site na impedance, mgbochi ahụ na ion migration impedance dị ntakịrị. N&39;ihe gbasara ịchaji, ngwugwu batrị lithium-ion adịghị nnukwu na okpomọkụ dị ala n&39;oge oyi, ọ dịkwa mkpa na ụgwọ okpomọkụ dị ala.

Because in horizontal flow ratio, 1C or 0.5C cross-flow ratio is very critical, to constant pressure to be very long, by improving three different graphite comparisons, one of which has a relatively large improvement in -20 degree charging constant flow ratio From 40% to 70%, the layer spacing is increased, and there is also a decrease in particle size. Nke a nke electrolyte, na -20 degrees, -30 degrees, electrolyte, ụba viscosity, na-emebi arụmọrụ.

Electrolyte sitere na akụkụ atọ: ihe mgbaze, nnu lithium, mgbakwunye. Ihe mgbaze nwere mmetụta dị ala nke okpomọkụ nke lithium iron phosphate ion batrị ngwugwu site na 70% ruo ihe karịrị 90%, yana ihe karịrị iri na abuo; nke abụọ, nnu lithium dị iche iche nwere mmetụta ụfọdụ na njirimara nke ụgwọ ọkụ dị ala na nkwụsị. Anyị na-edozi usoro ihe mgbaze na ntọala nnu lithium, ihe mgbakwunye okpomọkụ dị ala nwere ike ịbawanye ikike mgbapụta site na 85% ruo 90%, ya bụ, na usoro mmiri mmiri electrolytic dum, ihe mgbaze, nnu lithium na ihe mgbakwunye bụ obere okpomọkụ maka batrị lithium ike anyị.

Atụmatụ nwere mmetụta ụfọdụ, gụnyere usoro ihe ndị ọzọ. Adhesive, n&39;ọnọdụ nke ogo 20, a na-edozi isi ihe abụọ ahụ site na 70 ruo 80 okirikiri, na efere dum bụ ọnọdụ nke ọdịda nrapado, na eriri eriri adịghị adị. nsogbu a.

After the entire system, after the improvement of the positive electrode, the negative electrode, the electrolyte to the binder, the lithium phosphate ion battery monomer does better effect, one is charging characteristics, -20, -30, -40 degrees Temperature 0.5C charging constant current ratio can reach 62.9%, - 20 degree temperature discharge can be released 94%, this is some of the characteristics of the magnification and cycle.
